“…Extra oil recovery was observed after injecting 4–5 PV of biosurfactant solution, where 24–26% (≅0.5 ml) of So r was produced ( Figure 8 ). Other researchers have reported 20–37% additional oil recovery over the residual oil saturation using cell-free biosurfactant injection in the core-plugs or sand-pack columns (Yakimov et al, 1997; Almeida et al, 2004; Al-Sulaimani et al, 2011a; Darvishi et al, 2011; Joshi and Desai, 2013; Al-Wahaibi et al, 2014; Arora et al, 2014; Elshafie et al, 2015; Joshi et al, 2015; Jha et al, 2016). In present study, the additional oil recovered could be due to mechanisms like reduction in ST/IFT and/or due to wettability alteration at the rock-oil-water interface, as observed during the course of study.…”

The biosurfactant production by Bacillus licheniformis W16 and evaluation of biosurfactant based enhanced oil recovery (EOR) using core-flood under reservoir conditions were investigated. Previously reported nine different production media were screened for biosurfactant production, and two were further optimized with different carbon sources (glucose, sucrose, starch, cane molasses, or date molasses), as well as the strain was screened for biosurfactant production during the growth in different media. The biosurfactant reduced the surface tension and interfacial tension to 24.33 ± 0.57 mN m−1 and 2.47 ± 0.32 mN m−1 respectively within 72 h, at 40°C, and also altered the wettability of a hydrophobic surface by changing the contact angle from 55.67 ± 1.6 to 19.54°± 0.96°. The critical micelle dilution values of 4X were observed. The biosurfactants were characterized by different analytical techniques and identified as lipopeptide, similar to lichenysin-A. The biosurfactant was stable over wide range of extreme environmental conditions. The core flood experiments showed that the biosurfactant was able to enhance the oil recovery by 24–26% over residual oil saturation (Sor). The results highlight the potential application of lipopeptide biosurfactant in wettability alteration and microbial EOR processes.

“…1 μl of the sample-mixture was applied to the steel target plate, and air-dried at room temperature. The spectra were acquired using FlexControl software (v3.3), and FlexAnalysis Software (v3.3, Bruker Daltonics, Bremen, Germany) was used for visualization and initial data processing, as previously reported (Elshafie et al, 2015). …”

“…Kim et al [66] Elshafie et al [67] recently demonstrated biosurfactant producing C. bombicola ATCC 22214, for potential applications in oil recovery process. Production medium designed with glucose (2% w/v) and corn oil (10% v/v) successfully utilized by ATCC 22214 and demonstrated reduction in SFT (28.56+0.42 mN/m) and IFT (2.13+0.09 mN/m).…”

“…SPLs are quite stable at 13-15% salinity, pH of wide range (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12), and temperature upto 100°C. Elshafie et al [67] were successful to demonstrate the role of SPLs in enhancing oil recovery (27.27% of residual oil (Sor) recovery) using core-flooding experimental set up under reservoir conditions. Waste water resulting from dairy industries shows presence of high fat and oil content and therefore disposal of these effluents is extremely challenging.…”

Abstract:A strong developed bio-based industrial sector will significantly reduce dependency on fossil resources, help the countries meet climate change targets, and lead to greener and more environmental friendly growth. The key is to develop new technologies to sustainably transform renewable natural resources into bio-based products and biofuels. Biomass is a valuable resource and many parameters need to be taken in to account when assessing its use and the products made from its. The bioeconomy encompass the production of renewable biological resources and their conversion into food, feed and bio-based products (chemicals, materials and fuels) via innovative and efficient technologies provided by industrial biotechnology. The paper presents the smart and efficient way to use the agro-industrial, dairy and food processing wastes for biosurfactant's production. Clarification processes are mandatory to use the raw substrates for microbial growth as well as biosurfactant production for commercial purposes. At the same time it is very essential to retain the nutritional values of those cheap substrates. Broad industrial perspectives can be achieved when quality as well as the quantity of the biosurfactant is considered in great depth. Since substrates resulting from food processing, dairy, animal fat industries are not explored in great details; and hence are potential areas which can be explored thoroughly.

“…Sustainable development has been understood as a variety of concepts and indicators that have matured over time (Ciegis et al, 2015;Lopez et al, 2007;Tiwari and Ibrahim, 2012;Joshi et al, 2015, Frugoli et al, 2015. Particularly critical to wide impact is the shared meaning between global and national levels, which underpins much of the collaborative efforts in policy and business decision-making.…”

Mitigating the Davos dilemma: towards a global self-sustainability index

The' Davos dilemma' posits a sustainability crisis, provoked by rising human population and intense competitive behaviours, in terms of control and access to depleting natural resources. More broadly understood as an ecological problem, rather than just socio-economic behavioural deficiencies, it calls for better integrated social, natural and business indexed reporting within planetary boundaries. This poses challenges for nationally governed societies to equitably account for self-sustainability performance and their successive government agendas to re-orientate policies and industry investments as innovation towards achieving this in the longer term. We propose and test a Global self-sustainability index for countries across four metrics: economic, environmental, social and innovation. Our tentative findings from a cross-country analysis of twenty-seven countries during 2007-2010 illustrates the approach for wider systematic analysis and as a basis for future large-scale assessments on selfsustainability within and between countries.
